2. Description of the Related Art Heretofore, there has been, for example, a so-called through-diaphragm as a metal fitting for connecting a steel pipe column to a beam. In other words, for example, when a beam is attached to a square or round steel pipe column, as shown in FIG. F is butt-welded to the through-diaphragm D. The through-diaphragm D is connected to a steel pipe column 1 above it and a steel pipe 3 for a panel zone below it by butt welding. As described above, in the vicinity of the mounting position of the beam flange F in the peripheral portion of the diaphragm D, three welding portions are concentrated, and there is a possibility that the material performance of the diaphragm D is reduced due to heat input during welding. For this reason, in the conventional mounting position of the beam flange F, the peripheral portion of the diaphragm D is projected from the surface of the panel zone steel pipe 3 or the like by a predetermined amount to prevent the welding portion from being concentrated at one location. I was

In order to attach the beam to the column, the upper and lower two beam flanges F1 and F2 are welded to the corresponding diaphragms D, respectively, and the beam web W is connected to the panel zone steel pipe 3 by using the beam.
Is also attached by welding or the like. However, in this case, it is necessary to provide the scallops S as shown in FIG. 11 at positions near the ends of the beam flanges F in the beam web W. That is, as described above, since the peripheral portion of the diaphragm D protrudes from the panel zone steel pipe 3, there is a step between the peripheral portion and the surface of the panel zone steel pipe 3, and The main reason is that a backing metal 7 must be provided along the welding direction at the abutting position between the beam flange F and the diaphragm D.

However, the above-mentioned conventional beam attachment members for building structures have the following problems. When the scallop exists, stress tends to concentrate on the scallop during an earthquake or the like, and the scallop tends to be a source of fracture. For this reason, recently, what is called a non-scallop type column-beam joint structure in which scallops are not provided as much as possible is desired. The most rational method for achieving a non-scallop structure is to reduce the amount of projection of the diaphragm and make the end face of the diaphragm flush with the surface of the panel zone steel pipe. However, as described above, simply reducing the amount of protrusion of the diaphragm is not appropriate because it causes concentration of welding locations.

(Structure 1) As described in claim 1, in the metal fitting for connecting a steel pipe column to a beam of the present invention, a beam flange is connected to an outer side of an annular main body having an axis along a longitudinal direction of the steel pipe column. And a cylindrical section for joining the steel pipe column or the steel pipe for the panel zone is provided at both ends in a direction along the axis, and a direction along the axis. In view, the shortest distance from the shaft center in the beam joint surface portion, if the outer diameter of both the tube portions is different, from the shaft center of the peripheral portion in the tube portion with the larger outer diameter size If the outer diameter of both the cylinders is the same, set it to be equal to or less than the shortest distance from the shaft center of the peripheral part of either of the cylinders. It is characterized by the following points. (Operation / Effect) According to this configuration, a flat beam joining surface portion is provided on the outer side, and cylindrical portions are provided at both ends along the axis of the steel pipe column. Since the steel pipe column or the steel pipe for the panel zone is joined to each other, the respective joints can be separated from each other. For this reason, the material properties of the steel pipe column-beam joining hardware do not deteriorate due to heat input during welding. In addition, when the steel pipe column beam joining hardware is viewed in a direction along the axis of the steel tube column, the shortest distance from the axis of the steel tube column to the beam joining surface portion is different when the outer diameters of the two tube portions are different. Is equal to or shorter than the shortest distance of the peripheral portion of the cylindrical portion having the larger outer diameter from the axis. Therefore, when the panel zone steel pipe is joined to the cylindrical portion having the larger outer diameter, the substantially central portion of the beam joining surface is flush with the surface of the panel zone steel pipe, or the beam joining is performed. A substantially central portion of the surface portion is in a state of retreating from the surface of the panel zone steel pipe toward the axis of the steel pipe column, and as a result, the shape of the beam end also has a flange end and a web end in the longitudinal direction of the beam. Since the beams can be set at substantially the same position, the beam can be easily attached without the scallops. In addition, when the outer diameter dimension of both the tube parts is the same, when setting the shortest distance from the shaft center of the steel pipe column to the beam joint surface part, the shortest distance from the shaft center of the peripheral part in any tube part is set. The same result is obtained for distances, and the same operation and effect as described above can be obtained.

(Structure 2) According to a second aspect of the present invention, in the metal fitting for connecting a steel pipe column to a beam, a projection which can approach or abut a welding groove surface of a beam flange is formed substantially at the beam joining surface. It can be provided at the center. (Operation / Effect) As in the present configuration, if the projection is provided substantially at the center of the beam joining surface, the projection can be provided when the beam flange approaches or comes into contact with the steel pipe / column beam joining hardware. The part and the beam web will be located in substantially the same vertical plane. In this case, the welding groove formed at the end of the beam flange is divided by the projection, but each welding groove is welded to integrate the weld metal and the projection at each welding portion. As a result, it is possible to obtain the same welded joint as a result of welding the welding groove of the beam flange over the entire line. That is, in the case of the present configuration, welding work in a mode of passing through the beam web can be omitted, a reliable weld can be obtained while eliminating the need for advanced welding technology, and the occurrence of welding defects is also reduced. Can be prevented.

The metal pipe K for jointing steel pipes and columns of the present invention has, for example, an annular main body 2 whose planar shape is annular.
The vertical direction of the annular body 2, that is, the axis X of the annular body 2
At the both ends in the direction along, there is a tubular portion 4 for joining the steel pipe column 1 or the panel zone steel pipe 3. For this reason, in the present embodiment, the cylindrical portion 4 is substantially cylindrical. However, if the vertically connected steel tube column 1 is a so-called column column having a substantially rectangular shape, the steel tube column / beam joining hardware K is used.
And the shape of the cylindrical portion 4 are also adapted to the shape of the column. By providing the cylindrical portion, the connection between the steel pipe column connected vertically and the steel pipe for panel zone can be performed at the same level, so that the axial force in the axial direction of the column can be smoothly transmitted. In addition, since the connecting portion between the vertically connected steel pipe column and the steel pipe for the panel zone can be separated from the beam connecting surface 5, welding heat input does not concentrate at one place, and the proof strength of the annular body is reduced. No invite.

When the steel pipe column 1 to be connected to the steel pipe column / beam joining hardware K has a circular cross section, the mounting direction of the beam H can be arbitrarily determined. Therefore, in a building structure or the like in which the columns are exposed to the outside as well as the degree of freedom in designing the building structures, the round steel pipe columns exhibit excellent design properties. A predetermined number of beam joining surfaces 5 for welding the beam flange F are provided on the outer peripheral portion of the annular main body 2. Generally, four beams are connected to one connection part P at an angle of 90 degrees, respectively. Therefore, in the normal case, the annular main body 2 is also provided with four beam joining surfaces 5. . Further, the beam joining surface portion 5 is formed in a substantially linear shape when viewed in a planar direction. That is,
As shown in FIG. 2, the annular main body 2 has a plurality of planar beam joining surfaces 5 on the outer peripheral portion while exhibiting an overall annular shape. In FIG. 2, FIG. 2B is a diagram corresponding to II in FIG.
(C) is a cross-sectional view at a position, and FIG.
It is sectional drawing in the -II position. As a result of forming the beam joining surface portion 5 in a planar shape, the work of laying the beam between the previously erected columns becomes easy. This is because if the beam joining surface 5 is formed in a circumferential shape along the outer circumference of the cylindrical portion 4, the welding groove surface formed at the end of the beam flange F is also formed in a concave curved shape. Need to be done. In this case, when the beam is to be carried in between the columns from a horizontal row, there is a problem that the end of the beam flange F in the width direction interferes with the surface of the column. Therefore, for example, it is necessary to carry in the beam H in an inclined state, which not only complicates the carrying-in work, but also impairs the safety of the work. However, such inconvenience does not occur if the beam joining surface 5 is flat as in the present configuration.

As shown in FIG. 3, the beam joining surface 5 according to the present invention has a minimum distance from the axis X in the beam joining surface 5 when viewed in a direction along the axis X of the annular main body 2. For example, when the outer diameters of the two cylinders 4 are different, the cylinder 4 having the larger outer diameter of the two cylinders 4 is used.
Is set to be the same as the shortest distance of the peripheral portion from the axis X. As in the present embodiment, when the annular main body 2 has a shape adapted to a round steel pipe column, the beam joint surface portion 5 comes into contact with the outer peripheral portion of the cylindrical portion 4. Furthermore, while making the connection part P using two said annular main bodies 2,
FIG. 4 shows a state in which the beam H is attached to the connection portion P. In particular, the outer diameter of the panel zone steel pipe 3 is set to be the same as the outer diameter of the cylindrical portion 4 having the larger outer diameter, and
Is oriented such that the cylindrical portion 4 having the larger outer diameter faces the panel zone side. In this case, the central portion of the beam joining surface portion 5 provided on each annular main body 2 and the outer peripheral surface of the panel zone steel pipe 3 are substantially flush. With this configuration, as shown in FIG. 4, the ends of the upper flange F1 and the lower flange F2 can be formed substantially on the same line as the edge of the beam web W, and the scallops S need not be provided on the beam web W. In addition, attachment of the beam to the connection portion P becomes easy. In the case where the outer diameters of the two tubular portions 4 are the same, when setting the shortest distance from the axis X of the steel pipe column 1 to the beam joining surface portion 5, The result is the same even for the shortest distance from the axis X, and the same operation and effect as described above can be obtained.

At the end of the beam flange F, a groove is formed as shown in FIG. When the beam H is welded to the connection part P by field welding, the upper and lower flanges F1 and F2 are formed with a concave groove in the same direction so that downward welding can be performed. In addition, as shown in FIG. 4, the edge of the beam web W is made to protrude a predetermined distance from the groove bottom of the beam flange F. That is, when the beam H is brought into contact with the connection portion P and is temporarily fixed, and the end of the beam flange F and the annular main body 2 form the welding groove 6, the projecting length is equal to the welding groove 6. Is the route interval T of In the case of normal CO2 semi-automatic welding, the root interval T is approximately 9 mm. The backing metal 7 for welding is independently mounted on the left and right sides of the beam web W. The upper and lower flanges F1 and F2 are desirably located substantially at the center of the beam joining surface 5 in the vertical direction with respect to the corresponding beam joining surface 5 respectively. This is because, in the case of this configuration, the horizontal force from the beam H is most smoothly transmitted to the opposite beam. For this purpose, it is necessary to accurately set the mounting position of the annular main body 2 when forming the connection portion P.

Welding of the upper and lower flanges F1, F2 and the beam joint surface 5 is easy for the upper flange F1. FIG.
This is because, as is clear from FIG. On the other hand, at the time of welding the lower flange F2, the beam web W is present at the central portion in the longitudinal direction of the welding groove 6, but in the present embodiment, the scallops S for avoiding the beam web W are not provided. The welding work of the beam web W part becomes slightly complicated. For example, when complete penetration welding with the beam joining surface portion 5 is required over the entire width of the beam flange F, measures such as thinning the beam web W located near the beam flange F are required. Is required. This is because, by adopting this configuration, the welding portions from both sides can be reliably fused by welding from both sides of the beam web W. In addition, attachment of the backing metal 7 for welding to the lower flange F2 can be easily performed as shown in FIG. 4 without the beam web W becoming an obstacle. Also,
In both the upper flange F1 and the lower flange F2, the horizontal length of the beam joining surface portion 5 is set to the left and right with respect to the width of the beam flange F to be connected in order to secure an area for performing the end processing at the time of welding. It is a good idea to leave some room.

Can be secured. Therefore, when the end of the beam H is processed, the groove root portion of the flange F can be provided on the edge of the beam web W, so that the groove processing of the beam end is facilitated. For example, the beam member can be cut to a predetermined length using a band saw or the like, and then only the end of the flange F is beveled to form the welding groove 6. However, of the two cylindrical portions 4, the one with the larger outer diameter is the connection portion P
In order to secure the strength of the panel, it is often mounted on the panel zone side. Therefore, in the case of this another embodiment, the welding groove 6 provided on each of the upper and lower flanges F1, F2 is provided.
Must be formed in the direction opposite to the panel zone. If the welding groove 6 is formed in the same direction in both directions as in the above embodiment, the step 9 between the beam joining surface 5 and the outer periphery of the cylindrical portion 4 is formed in the welding groove 6 of the lower flange F2.

<2> In the above embodiment, particularly, the description has been made that the welding between the lower flange F2 and the beam joining surface portion 5 is somewhat complicated. However, the joining of both can be performed in the following manner. For example, the configuration is as shown in FIG. That is, a projection 11 having an inclined portion 10 corresponding to the groove angle of the flange is formed substantially at the center of the beam joining surface 5. on the other hand,
The groove of the lower flange F2 is formed over the entire width, and the notch 12 is formed at the lower end of the beam web W. The protrusion 11 is close to the groove surface of the beam flange F, or
It is configured so that it can be abutted and fits well in the notch 12 of the beam web W. Further, it is desirable that the thickness of the projection 11 be as thin as possible. However, the thickness of the projection 11 is such that when the first welding is performed from one side of the projection 11, the projection 11 does not melt off due to the heat input of welding. It is desirable that the two welds are of such a degree that they can be melted into each other by welding from both sides. To this end, the shape of the lower end portion of the beam web W is also processed to be thin so as to match the thickness of the projection 11 as shown in FIG.
With this configuration, it is possible to perform full penetration welding of the lower flange F2 over its entire width.

For example, FIG. 8 shows a case in which it is attached to a stepped connection portion P1 having three annular main bodies 2. In this case, with respect to the annular main body 2 inserted in the middle, it is not necessary to provide the beam joining surface portion 5 in a portion where the beam flange F is not welded. That is, for the beam H for welding the beam flange F to the upper and lower annular bodies 2 above the intermediate annular body 2, it is sufficient to consider fixing only the beam web W to the intermediate annular body 2. It is. In particular,
As shown in FIG. 8, the portion corresponding to the beam web W is:
What is necessary is just to comprise it as a cylindrical surface shape. As a result, the outer surfaces of the annular main body 2 provided in the middle and the panel zone steel pipes 3 which are welded and connected at the top and bottom thereof are flush with each other. Therefore,
Even in the case of the beam H to which the beam flange F is attached over the uppermost annular body 2 and the lowermost annular body 2, the beam web W of the beam H is formed by the two panel zone steel pipes 3 and the intermediate annular body. 2, and can form a non-scallop type stepped connection part P1.
